Problems solved by technology

At present, most of the existing domestic flame-retardant materials and cable samples constructed with flame-retardant technology are difficult to pass the EU B standard. 1 Assessment of Class Flame Retardant Cables
The cross-linked polyethylene material used as cable insulation has high electric strength and good manufacturing process, but it is flammable and has a large amount of heat release. For this reason, the usual measure is to wrap multi-layer metal tapes on the cable or place a thicker flame-resistant material. materials to weaken the attack of the high temperature of the external flame, but this increases the production cost and difficulty

Embodiment 1

[0020] A high flame-retardant cable, comprising a conductor layer (1), a flame-retardant tube (2) and a sheath layer (3); the conductor layer (1) includes at least one conductor unit, and the conductor unit includes a conductor and The insulation layer wrapped on the conductor, each of the conductor units is enclosed to form a bundle structure and surrounded by a flame-retardant tube, and the flame-retardant tube is filled with a flame-retardant material (21); the sheath layer includes A tape layer, a silicon rubber layer and an outer sheath layer are attached in sequence, the thickness of the silicon rubber layer is 2 mm; the tape layer is wrapped around the outer wall of the beam structure.

[0021] Further, in a highly flame-resistant cable, the number of said conductor units is 6.

[0022] Further, in a highly flame-resistant cable, the number of the flame-retardant tube (2) is one.

[0023] Further, in a highly flame-resistant cable, the conductor (11) is a copper core c...

Embodiment 2

[0032] This embodiment will give different ways of setting flame retardant materials. In the high flame retardant cables of this embodiment, as in figure 2 As shown in , 1 is the conductor layer. The number of conductor units is 7, and its cross section is circular. The other 6 conductor units are evenly distributed on the periphery of one conductor unit. The outer surface of one conductor unit is tangent to the outer surfaces of the other six conductor units; the outer surfaces of the other six conductor units are connected in tangent in pairs, and the center forms a hexagon. Each conductor unit is surrounded to form a bundle structure. The conductor unit also includes a conductor 11 and an insulating layer 12 . The insulating layer 12 covers the periphery of the conductor 11 . The insulating layer 12 is made of cross-linked polyethylene, and the conductor 11 is made of copper. Layers of cross-linked polyethylene material resist moisture, seal and electrically insulate....

Abstract

A high flame-retardant cable is provided. The high flame-retardant cable comprises a conductor layer, a flame-retardant tube and a sheath layer. The conductor layer comprises at least one conductor unit; the conductor unit comprises a conductor and an insulating layer wrapped around the conductor; each conductor unit is enclosed to form a bundle structure and surrounds the flame-retardant tube; the flame-retardant tube is filled with a flame-retardant material; the sheath layer comprises a belt layer, a silicone rubber layer and an outer sheath layer which are sequentially attached from the inside to the outside; the thickness of the silicone rubber layer is 2 mm; and the belt layer is wrapped around the outer wall of the bundle structure.

Description

technical field [0001] The invention relates to a cable, in particular to a high flame-retardant cable. Background technique [0002] With the improvement of people's requirements for the safety of electricity use, the flame retardant performance of cables has attracted more and more attention, and its quality directly affects the safety of users. At present, the main cables on the market are ordinary cables whose structure mainly includes conductors, insulators, ordinary fillers, and sheaths. The material of the insulator generally adopts cross-linked polyethylene insulating material. Since the material is flammable and there is no good protective layer around the insulation, the flame resistance of the cable is not good. Halogen-free, non-toxic, low heat release and high self-extinguishing characteristics of cables have become the goals of colleagues in the industry--EU B 1 The assessment method of grade flame retardant cable is the benchmark to measure whether this goa...
